JVC’s native 4K D-ILA-based DLA-RS4500 projector.
JVC used CEDIA Expo 2016 to unveil its first “native 4K” D-ILA video projector with laser light engine designed to compete directly with Sony’s native 4K SXRD models.
The new flagship JVC Reference Series DLA-RS4500 incorporates a JVC-developed native 4K D-ILA system with three 0.69-inch LCoS microdisplay chips (one each for red, green and blue). Each chip has a 3.8 ㎛ pixel gap, which is said to be 31 percent more narrow than the gap in earlier D-ILA devices.
JVC said the new native 4K video projector is directed at the home theater market and uses JVC’s proprietary “BLU-Escent” laser phosphor light source that is capable of 3,000 lumens of brightness and up to 20,000-hours of operational life.
The JVC Reference Series DLA-RS4500 will be available in December through authorized Reference Series dealers and installers for a $34,999.95 suggested retail price.

The JVC DLA-RS4500 employs a dynamic light control that is said to produce highly bright images with high contrast. JVC is calling the performance levels “the highest native contrast available.” JVC said the levels are large enough to support images with high dynamic range (HDR).
By using both vertical orientation technology and planarization techniques in the DLA-RS4500, scattering and light diffraction have been decreased, which enhances contrast. The result is said to be a smooth, detailed image with no visible pixel structure, even when using large screens.
Other features in the DLA-RS4500 include: a new high-resolution lens developed specifically for 4K applications and a Cinema Filter to produce a wide color gamut.
For a number of years JVC has made and marketed several generations of D-ILA projectors using its 2K LCoS microdisplay chips and various levels of what it calls its e-shift technology. This technology essentially rapidly shifted pixels slightly back and forth in sequence to make the eye perceive a single 4K-like image. Later generations of JVC e-shift projectors accepted 4K native source input, which the projectors could display to their maximum capabilities. Similar techniques were later developed by manufacturers of 3LCD and DLP microdisplay devices for use in their respective projector technologies.
To boost brightness and contrast, JVC is also using its second-generation BLU-Escent laser light engine in the DLA-RS4500. This uses blue laser diodes to offer a brightness level of 3,000 lumens and 20,000 hours of operational life. The laser unit employs six banks of eight laser diodes to achieve its high brightness levels, and a stationary emissive phosphor, which reduces mechanical noise and enhances reliability. The company said the high brightness allows the projector to be used with screen sizes over 200 inches and makes the most of HDR to deliver an image with depth and richness.

The laser engine enables the DLA-RS4500 to control laser output dynamically, adjusting output instantly based on the scene to provide bright whites, deep darks and brilliant colors. The Dynamic Light Source Control is aid to achieve a contrast ratio of ∞:1.
The JVC projector will also accept a very wide color gamut. The company said the DLA-RS4500 will achieve 100 percent of the DCI-P3 color space and up to 80 percent of the B.T.-2020 space. “This allows subtle gradations, such as of the sky or the sea, to be vividly reproduced,” JVC said.
To maximize sharpness and detail JVC has developed a new all-glass lens with 18-elements and 16-groups with full aluminum lens barrel. A new 100mm diameter lens is used for best light efficiency and to project 4K resolution to every corner of the screen. This compares to 65mm diameter designs used in other JVC projectors.
The new lens is said to have an expanded shift range of ±100 percent vertical and ±43 percent horizontal. Using five anomalous dispersion lenses JVC claims to have reduced chromatic aberration and color fringing for precise 4K resolution graphics.
For HDR, the DLA-RS4500 produces an extended brightness range, 10-bit gradation and wide BT.2020 color gamut, which place high demands on display devices. When the projector detects an HDR signal it automatically selects the correct picture mode preset based on the HDR 10 HDR format. JVC said the DLA-RS4500 also be able to support Hybrid Log-Gamma (HLG), which was developed by the BBC and NHK for live HDR broadcasts and streaming. That HDR system will been approved for use in European broadcasts, but its use in the U.S. has not yet been determined.
Other features in the DLA-RS4500 include an all-new cosmetic design, with a symmetrical matte black aluminum cabinet. The center-mounted lens is set off from the black body by a gold ring. For cooling, the rear intake/front exhaust fan adapts to the installation environment to maximize its effectiveness, and it employs a professional level air filter that can withstand severe conditions.
JVC said the DLA-RS4500 will be the world’s first THX Certified 4K projector, and will have two full-speed 18Gbps HDMI 2.0a inputs with HDR and HDCP 2.2.
JVC’s Multiple Pixel Control employs a new algorithm optimized for the new 4K device to produce detailed images even when converted from Full HD images.
To reduce motion blurring, the DLA-RS4500 features JVC’s Clear Motion Drive technology, which is compatible with 4K60p (4:4:4), and Motion Enhance, which minimizes motion blur by optimizing the D-ILA driver. The two technologies, working together, result in a smooth and detailed image.
An on-board screen adjust mode optimizes color and performance for different screen materials, while the projector’s Low Latency Mode decreases input lag from source devices like gaming consoles.
Ten preset installation modes combine settings for Lens Memory, Pixel Adjust, Screen Mask and other parameters to customize settings for the best installation.
